-Hawkins lost one life because he was looking at Luffy, Zoro cheap-shotted him from the rear.
-The other one came after Hawkins damaged Zoro with nails, which come through his straw puppet, not via his own body
No one ever said Hawkins is all about his stored lives. We've seen that Hawkins can use Haki when he blocked Law's sword, and if he is not like Cracker, then he has his own durability and stamina as well, in addition to his own CoA defense. Of course he couldn't take both Luffy + Zoro at the same time, but even then overpowering Zoro while Luffy was there was impressive.
I am not salty, I just said E.Oda wouldn't be consistent if Zoro solo fights King, and Luffy solo fights Kaido at this point. In comparison with pre-time skip, they weren't struggling of the minions of their main opponents, Zoro for one, defeated T-Bone without taking any damage before fighting with Kaku. In here, he already took a damage from Apoo, and if Hawkins was there, he could take nails again as a damage.
